Culinary weblog and discussion forum Chowhound gives a great tip to help refresh stale chips when you bring your Mexican dinner leftovers to the office for lunch the next day. Simply lay your tortilla chips on a paper towel and microwave them on high for 30 seconds.

Moisture is what makes the chips soggy; microwaving them for 30 seconds evaporate away the moisture on the chips. They won't be as good as they were originally, but they'll be way better than the stale chips you had before microwaving.

I just ran a trail of this method and the microwaved chips were definitely less stale. Give it a try.
